Are you interested in trying out RCov? Are you unsure of how to start? Are you looking to improve the RCov-fu on your project? I have just the solution for you! I have started a project that demonstrates different RCov configurations for different testing frameworks. This project is meant to help spread RCov related knowledge. You can get the bits by running:
git clone git://github.com/abedra/rcov-examples.git
Feel free to browse around and submit any feedback. I am hoping to get as many samples in as possible, so feel free to contribute!
